iommu/amd: Remove conditions from domain free paths

Browse source

Don't use tlb as some flag to indicate if protection_domain_alloc()
completed. Have protection_domain_alloc() unwind itself in the normal
kernel style and require protection_domain_free() only be called on
successful results of protection_domain_alloc().

Also, the amd_iommu_domain_free() op is never called by the core code with
a NULL argument, so remove all the NULL tests as well.
